SPECIFICATION forming part of Letters Patent No. 319,343, dated June 2, 1885.

Application led September 23, 1884. (No model.)

To all whom t may concern: I

Be it known that I, ALBERT STRAUB, of Gowanda, in the county of Erie and State of New York, have invented new and useful Improvements in Carriage-Springs, of which the following is a specification.

This invention relates to van improvement in that class of carriage-springs which are composed of side springs and cross-springs which connect the side springs, and4 upon which the body of the wagon or carriage is supported.

The object of my invention is to connect the cross and side springs in such manner that they are free from any torsional strain.

My invention consists to this end ofthe in1- provements which will be hereinafter fully dcscribed, and pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation of my improved carriagespring. Fig. 2 is a top plan view of the same. Fig. 3 is a fragmentarylongitudinal section, on an enlarged scale, of one of the side springs and the couplings whereby the side springs are connected with the bolster and crosssprings. Fig. 4 is a cross-section in line w m, Fig. 3. Fig. 5 is a perspective view of the coupling whereby the side springs are connected to the bolster and the side and cross springs are connected together.

Like letters of reference refer to like parts in the several figures.

A represents the front axle; B, the rear axle, and C the bolster secured to the front axle.

D represents the side springs,which are attached with their front ends to the bolster C and with their rear ends to the axle B.

E represents the cross-springs, which connect the side springs, and are arranged between the axles A B, and upon which the body or box is supported.

The front ends of the side springs, D, are connected to the bolster C by means of shackles or links d and clips d, and their rear ends are connected to the rear axle, B, by clips b.

The clip-bar d2 of the clip d is formed with a depression or cavity, d3, in which rests the cross-bar d* of the shackle d. The shackle d is free to swing in the cavity formed in the clip-plate, whereby the forward end of the side spring is permitted to move forward or backward on the clip, and the spring thereby relieved from strain. This construction also prevents the shackle d from binding between the clip-bar and bolster, and avoids the necessity of forming a recess in the bolster for receiving the cross-bar ofthe shackle.

F represents the coupling whereby the cross-springs are connected with the side springs. This coupling consists of two cylindrical sockets or holes, f f', arranged at right angles to eachother and in different parallel planes. The upper socket, f, of the coupling is arranged between two downwardly-projecting lugs or ears, g g, formed on the upper leaf of the side springs and pivoted between the same by a bolt or pin, y', passing through the ears and socket.

h h represent two parallel bars or links, which are arranged on opposite sides of the lower socket, f, and connected at their upper ends by a bolt, h, passing through the socket f. The lower ends of the links 7L are connected by a bolt or pin, c', and the end of the cross-spring is pivoted to the bolt z' be tween the links 7L h. This construction permits the cross-springs to move outwardly, as they are deflected without imparting any torsional strain to the side springs, and the latter are free to move forwardly without straining the cross-springs.

The lugs or ears gig/,being formed on the upper leaf of the side spring, permit the several leaves of the spring to move freely upon each other, and also serve to hold the several leaves against lateral displacement.

I claim as my invention- 1. The combination, with the side springs, D, having downwardlydepending lugs g, of the cross-springs E and coupling F, provided with sockets fj", whereby the cross-springs are connected to the side springs, substantially as set forth.

2. The combination, with the side springs, D, having downwardly-depending lugs g, of the cross-springs E and coupling F provided with asocket, j", pivoted between the `lugs g by a bolt, g', and a socket, f', arranged at right angles to the socket f and pivoted to the cross-springs E by links 7i hand bolt z', substantially as set forth.
